Hi everyone,

 

I have DWG files drawn in local coordinates and I need to transform them to shapefiles in a national projected coordinate system. This is currently done with Spatial Adjustment (Transformation - Similarity) as the links file (.txt) provided has two displacement links:

 

-1000 -1000 "Destination X Value" "Destination Y Value"

1000 1000 "Destination X Value" "Destination Y Value"

 

p.s. I've just replaced actual numbers by "Destination X Value" etc.

 

What would be the best way to replicate this process with FME? If it is Affiner how do I utilise the values from the links file?

 

Thanks in advance!

The Offsetter transformer will allow you to translate the feature(s) in Cartesian coordinates.

You also have the Affine and AffineWarper transformers that will allow for some more complex adjustments
